  • Adopting Collaborative Workflow Pattern: Use Case
    Antonio Capodieci, Giuseppe Del Fiore and Luca Mainetti,University of Salento,Italy
    In recent years, the use of web 2.0 tools has increased in companies and organisation. This phenomenon, has modified common organisational and operative practices. This has led “knowledge workers” to change their working practices through the use of Web 2.0 communication tools. Unfortunately, these tools have not been integrated with existing enterprise information systems. This is an important problem in an organisational context, because knowledge of information exchanged within the organisation is needed to increase the efficiency and competitiveness of the organisation. In previous works we demonstrate that it is possible to capture this knowledge using collaboration processes, which are processes of abstraction created in accordance with design patterns and applied to new organisational operative practices. In this article, we want to present the experience of the adoption of the methodology and the catalog of patterns from some pattern designers of a company operating in Public Administration and Finance, with the aim of shaping an information system Enterprise 2.0, which takes into account the collaborative processes.
  • A learning design repository for supporting reuse
    Azeddine Chikh,King Saud University,Saudi Arabia
    Former research on learning objects has targeted either learners, as consumers of these objects, or teachers, as developers who reuse these objects as educational resources in new courses. Recently a new need has come for sharing and reusing learning design related knowledge. Our main goal in this work is to increase the level of reusability of learning design related knowledge, either theoretical or practical, in designing new online courses. We first define a new concept of learning design object. The primary aim of this concept is to elucidate how we can develop a set of more powerful learning objects targeted to support teachers in their design activities. We then use a class diagram to facilitate the representation of the general model of a repository of learning design objects. Furthermore we illustrate the usefulness of the proposed repository through a learning design support framework.
  • Automated Model in the Loop for Embedded Systems Testing
    Samaa A. Abdel Samie,Ain Shams University,Egypt
    Organ segmentation from medical images is still an open problem and liver segmentation is a much more challenging task among other organ segmentations. This paper presents a liver segmentation method from a sequence of computer tomography images. We propose a novel balloon force that controls the direction of the evolution process and slows down the evolving contour in regions with weak or without edges and discourages the evolving contour from going far away from the liver boundary or from leaking at a region that has a weak edge, or does not have an edge. The model is implemented using a modified Distance Regularized Level Set (DRLS) model. The experimental results show that the method can achieve a satisfactory result. Comparing with the original DRLS model, our model is more effective in dealing with over segmentation problems.
  • An IWD Algorithm for Discrete Time, Cost and Quality Trade -off in Software Projects
    Abdulelah G. Saif, Safia Abbas and Zaki,Ain Shams University,Egypt
    Software project manager's goal is getting an optimal allocation of time, cost and quality of each task/activity in the software project such that total time and cost of the project is minimized while project quality is maximized. To achieve this goal, this research paper adapts intelligent water drops (IWD) algorithm to solve the discrete time- cost-quality trade-off problem (DTCQTP) in software projects which is never solved before by this algorithm. IWD algorithm decides the preferred modes of performing tasks where task quality is expressed quantitatively in terms of defects. An example is given at the end to show the trade-off analysis between project's cost, time and quality. Keywords— Time cost quality trade-off, Project scheduling, swarm intelligence, Software defect origins, Software projects
  • Distributed Scrum When Turning Into Maintenance:A Single Case Study
    Minna Kilpala and Tommi Karkkainen,Jyväskylä University,Finland
    Global software development using agile methods is commonplace in software industry nowadays. Scrum, as the agile development management framework, can be distributed in many ways, especially concerning how the key roles are presented in different sites. We describe here a single case study of a distributed Scrum, mainly for maintenance of the already constructed web portal. Using a qualitative method, both working well and challenging parts of the software work, as experienced by the project stakeholders, are revealed and discussed.
